Today I put the spindle bearings in, taking great care not to balls things up, as they need to go in back-to-back.
Once the spindle was in, I could insert the pinion gear and shaft, the clutch and then the quill feed forward/reverse drive shaft and then the feed gear shaft and the worm gear cradle. All went well until I found out that the pinion shaft is bent
I looked over the print for the quill feed engagement part as I was to start making it yesterday. I found that I need some help with extrapolating some dimensions, but I no longer have a working copy of AutoCad2000 to do it.
What I need is the X-Y coordinate values for the angles coming off the 25mm radius, out to the 60mm width. Kondia clearly used a casting that would have had those dimensions, so we'll have to figure them out. Got any ideas?
Other that that, I've decided to run up to BTS-Patriot Steels in Dover NH to get a couple of pieces of 4142 pre-treated stock to make the part. Of course I only need one piece, but you know Murphy's Law, subchapter C, paragraph 5, "If you have a spare piece of stock you won't need it, it you don't have a spare you WILL need it."

Hi Ken,
I'm not confident that I have understood your question but I have had a go! I used DraftSight, which is free and easy enough that I can use it!
Attached is my interpretation of the angle you are after. I don't think that I originally posted the Kondia drawing, as I was concerned regarding copyright. However, Kondia have released the drawing to me as they no longer manufacturer these parts, so it may be OK to do so. Ed - what do you think?
In the meantime, if you want to look at the Kondia drawing, please PM me...
Dimension from the center of the 25mm radius to the end points of radius where it meets the angles. Using the center of the 25mm radius would be fine. I can shift from there if needed.
Perfect! As soon as I can get the better material I can start. So sorry for the delays, it's been a VERY busy time for me.
I had to grind 3 more of those blocks for a friend in a big hurry yesterday because the hardened ones I did last weekend were cracked from poor heat treating. This time he convinced his customer to take them in the annealed condition because it's base for a static gauge, not a high speed working press tool or anything like that.
